Understand Critical Deceleration
Useful when…
- Raise critical chance on a compatible shotgun when the fire-rate penalty is acceptable.
- Use a partial rank for a smaller critical chance bonus and fire-rate reduction.
Rank effects
At rank 0, Critical Deceleration grants +33.3% critical chance and -3.3% fire rate. At rank 3, it grants +133.3% critical chance and -13.3% fire rate; at rank 5, it grants +200% critical chance and -20% fire rate. Both effects increase together as the mod is ranked.
Compatibility and stats
This is a standard shotgun mod with Madurai polarity and base drain 4. It is incompatible with the named mods Blunderbuss and Flawed Blunderbuss. Blunderbuss provides +90% critical chance, while Flawed Blunderbuss provides +40%; neither description lists a fire-rate effect. Accelerated Blast instead provides +60% fire rate and +60% Puncture.
Ranking and fusion costs
The maximum rank is 5. Rank 3 provides +133.3% critical chance and -13.3% fire rate. The example cost for the rank 2-to-3 step is 120 Endo and 5,796 Credits; the rank 4-to-5 step costs 480 Endo and 23,184 Credits. A lower rank gives smaller listed bonuses and penalties than rank 5.
